In this article, we analyze the canonical hold-up model of Hart and Moore under the assumption that the courts can verify delivery of the good by the seller. It is shown that no further renegotiation design is necessary to achieve the first best: simple option contracts, which give the seller...

The privatization process in Eastern Europe is not irreversible. Future governments may want to (partially) expropriate successful private firms in order to subsidize unsuccessful ones. We use a simple median voter model to predict the policy of future governments. It is shown that there will be...

In some markets vertically integrated firms sell directly to final customers but also to independent downstream firms with whom they then compete on the downstream market. It is often argued that resellers intensify competition and benefit consumers, in particular when wholesale prices are...

This paper studies the relation between discrete-time and continuous-time principal-agent models. We derive the continuous-time model as a limit of discrete-time models with ever shorter periods and show that optimal incentive schemes in the discrete-time models approximate the optimal incentive...

This paper offers a new explanation for the prevalent use of convertible securities in venture capital finance. Convertible securities can be used to endogenously allocate cash-flow rights as a function of the state of the world and the entrepreneur's effort. This property can be used to induce...

Most economic models are based on the self-interest hypothesis that assumes that material self-interest exclusively motivates all people. Experimental economists have gathered overwhelming evidence in recent years, however, that systematically refutes the self-interest hypothesis, suggesting...

Technological standards give rise to a complements problem that affects pricing and innovation incentives of technology producers. In this paper I discuss how patent pools can be used to solve these problems and what incentives patent holders have to form a patent pool. I offer some suggestions...

Many high technology goods are based on standards that require several essential patents owned by different IP holders. This gives rise to a complements and a double mark-up problem. We compare the welfare effects of two different business strategies dealing with these problems. Vertical...
